Water boils at 10°c when it placed at 27km above ground.why

Why It Matters

Understanding how boiling points change with altitude has real-world applications in science, engineering, and even survival:

🔬 Scientific Research
High-altitude environments, such as the upper atmosphere or space simulations, help scientists study how materials behave under low-pressure conditions. Knowing that water boils at just 10°C at 27 km altitude is crucial for designing experiments in high-altitude balloons or spacecraft systems.

🚀 Aerospace & Space Exploration
Spacecraft and high-altitude aircraft must account for pressure changes when managing fluids like water or fuel. Engineers must design systems that prevent unintended boiling or freezing at such low pressures.

🥾 Mountain Climbing & Survival
Even on Earth’s tallest peaks (much lower than 27 km), climbers face the challenge of boiling water at lower temperatures, which can affect cooking and sanitation. While 10°C boiling is extreme and doesn’t occur until the stratosphere, the concept helps explain why boiling food takes longer or may not sterilize effectively at high altitudes.

🌍 Climate and Atmospheric Studies
Atmospheric pressure variations impact everything from weather patterns to climate models. Understanding physical behavior like phase changes at specific altitudes contributes to better models of Earth’s atmosphere.
